WILLIAM F. CREMEAN, OF \VILKES-BARRE, PENNSYLVANIA.

RAILWAY-CAR.

Specification of Letters Patent.

Patented Apr. 6, 1920.

Application filed May 3, 1919. Serial No. 294,369.

To all whom it may concern:

Be it known that I, VVILLIAM F. CRE- nnsx, a citizen of the UnitedStates, residing at W'ilkes-Barre, in the county of Luzerne and State ofPennsylvania, have invented new and useful Improvements in Railway-Cars,of which the following is a specification.

This invention relates to railway cars of the drop bottom or hopperbottom type, and in particular to an improved arrangement of doorsecuring parts and lifting and locking mechanism.

Heretofore difliculties have been experienced in the complete closing ofthe doors of hopper bottom cars, due to the warping or springing of thedoors and to other causes, so that considerable loss of ore, coal orother material loaded on the car occurred, due to spillage through theunclosed spaces between the partly closed doors and the car bottom. Forexample, in the hopper door appliances now generally in use, it is oftenfound impossible to properly close the doors, when these are warped orsprung, as the door securing latch or hook, as at present shaped, ofteneither cannot be brought to engage the door at all, or hold it snugagainst the hopper bottom.

The object of my invention is to avoid these and other difliculties byproviding mechanism by which a door that does not close properly may beconveniently and quickly lifted into place and securely locked.

Other objects of the invention will manifest themselves from thedetailed description thereof and manner of applying and using the sameto be presently disclosed.

The invention consists of structural characteristics and relativearrangements of elements which will be hereinafter more fully describedand particularly pointed out in appended claims.

In the drawings, in which similar reference characters indicate the sameparts in the several figures,

Figure 1 is a side elevational view of one form of the hopper doorsecuring device and portion of a car to which it is attached;

Fig. 2 is asectional view taken on line II-II of Fig. 1;

Fig. 3 is a vertical sectional view taken on line IIIIII of Fig. 1;

Fig. a is a side elevational view of a modified form of my device, and

Fig. 5 is a sectional view taken on line VV of Fig. 4;

In the drawings, the car body is represented as having sides 10 and ahopper bottom provided with the usual discharge opening not shown.Adapted to close the latter and fastened to the hopper bottom a pair oftransversely disposed, hinged doors 11 are provided. These doors arelocated with their free edges adjacent each other and are supported onlong hinge bars 12, movable on pintles 13 disposed transversely of thecar and so that the doors are adapted to swing toward each other intoclosed position.

Fastened to the lower sides near the inner edges of each of the doorsare angle-irons 14 serving to stiffen the doors and extended outwardly ashort distance beyond the latter, on each side, so as to provideconvenient ledges to be engaged by the door hooks 15. These hooks areprovided with integral pivot lugs 16 j ournaled in outer and innerbrackets 17 and 18, respectively, which are riveted to the car sides 10.The hooks for each pair of doors are turned to swing parallel with theside of the car toward the free edges of the doors, in oppositedirections, and are adapted to engage the angle irons 14 of the doors,being pivoted with respect to their centers of gravity so that they willfall by gravity into engaging positions.

The locking face or supporting ledge 19 and the auxiliary supportingface or ledge 20 of each hook are shaped to conform to the flat leg orlooking face of the projecting angle iron 14, and are so disposed that avertical plane drawn through the axis of the pivots will be normal tothe locking faces when the doors are closed. The hooks therefore tend tohold the doors closed.

Each hook 15 is provided on its lower rear edge with a lug or projectingportion 21 adapted to serve as a bearing or fulcrum for liftin the doorinto a closed position. In the modification shown in Fig. at, this lugor projection is provided on the outer lower side of the hook and isindicated by the numeral 22. In this modification also the auxiliarysupporting face 20 of Fig. 1 is not incorporated.

A gravity eccentric cam 23, pivoted to the car side on the bolt 24, issupplied for each hook for the purpose of firmly and securely lockingthe hooks and therefore the doors in their closed position in everyposition of the car and while it is being transported from mine todestination.

The operation of my lifting and locking mechanism is as follows: When,as often happens, the hopper bottom door will not close completely, asshown on the left side of Fig. 1, it may be held on the auxiliarysupporting face or ledge 20 of the hook, while being lifted by hand toits normal closed position by means of a bar 13, fulcrumed on the lug21, the door being raised from the supporting face 20 until it rests onthe locking face 19, and finally pushed home, as shown on the right sideof Fig. 1. The bar B in Fig. 1 is of course held ap proximately normalto the plane of the car side.

In the modification of my device, shown in Fig. 4, when the uncloseddoor is in the position shown on the right side of Fig. l, the bar B isheld approximately parallr-zl to the side of the car, fulcrumed on thelug 22 and engaged with the flat leg of the angleiron l i. lowering theouter end of the bar B the door may readily be lifted to the positionshown on the left side of F 4; and securely locked in position.

It is obvious that various other forms and modifications may be madewithout depart ing from the essential features and principle of myinvention and I do not wish to be understood as limiting myself to thespecific and preferred construction. herein shown and described.

lVhat I claim is 1. As a new article of manufacture in hopper bottomdoor securing devices, a pivoted hopper bottom door engaging hookprovided with a door engaging ledge, an auxiliary supporting ledgelocated below the former and a lug or projecting portion adapted toserve as a support for means for raising the door from support on thelatter ledge to the former.

2. The combination of hopper bottom car doors and securing devicescomprising door engaging hooks, each provided with a door engaging ledgeand a lug or projecting portion adapted to serve as a support formovable door raising means and coacting with said ledge.

In hopper bottom car door securing devices, a hook having door engagingmeans and provided with a projecting portion so constructed and arrangedas to be adapted to receive movable door raising means and serve as afulcrum therefor.

i. A railway car having a movable door, a hook pivoted to the car andadapted to engage said door and to hold the same in closed position, acam also pivoted to the car and adapted to hold the said hook in engagedrelationship with the door, the said hook being provided with anauxiliary ledge and a projecting portion by means of which the door maybe raised from a partly closed to a fully closed position.

5. ll railway car having a body and movable door, an outer bracketattached to and spaced from the outer side of the body, a hook havingintegral and oppositely disposed pivot lugs journaled in said outerbracket and car body and adapted to engage said door and hold the samein closed posi tion.

6. A railway car having a body and movable door, an outer bracketattached to and spaced from the outer side of the body, an inner bracketattached to the inner side of the body, a hook having integral andoppositely disposed pivot lugs journaled in said outer and innerbrackets and adapted to engage said door and hold. the same in closedposition.

In testimony whereof I aflix my signature.

WVILLIAM F. OREMEAN.
